Dr. Thomas Passler is an associate professor in the Department of Clinical Sciences where his responsibilities include the management of hospitalized and out-patient cases, teaching, research, service, and outreach.
Dr. Passler was born and raised in Berlin, Germany, and completed his veterinary training at the Free University, Berlin, in 2003. Following two years in private mixed-animal practice, Dr. Passler joined the team of veterinarians in Auburn’s food animal section as a resident of large animal internal medicine. In 2008, he became board-certified as a diplomate of the American College of Veterinary Internal Medicine and subsequently became a faculty member.
Dr. Passler’s clinical and research interests include the medical and infectious diseases of large and small ruminants and camelids. His research has primarily concentrated on the infectious pathogen Bovine viral diarrhea virus (BVDV) with a focus on BVDV infections in white-tailed deer. Specific interests include the epidemiology and pathophysiology of BVDV infections in heterologous species and their impact on the control of BVDV in cattle populations. Furthermore, Dr. Passler is interested in furthering the knowledge on the pathophysiology of diseases affecting domestic and wild ruminants, and camelids.
